elevated ICP is most commonly associated with _______
head injury
brains ability to change the diameter of its blood vessels to maintain a constant cerebral blood flow
autoregulation
seen when cerebral blood flow decreases significantly
cushing’s response
earliest sign for ICP

provides information about cerebral blood flow
transcranial blood flow
involves the opening of the skull surgically to gain access to intracranial structures
craniotomy
this is performed to REMOVE A TUMOR, relieved elevated ICP, evacuate a BLOOD CLOT, or control hemorrhage
craniotomy
excision of a portion of the skull

two main types of seizures:
partial seizures
generalized seizures
seizures that begin in ONE PART of the brain
partial seizures
seizures that involve electrical discharges in the WHOLE brain
generalized seizures
TYPES OF PARTIAL SEIZURES
simple partial seizure
complex partial seizure
seizures with ELEMENTARY symptoms, generally WITHOUT impairment of consciousness
simple partial seizures
seizures with COMPLEX symptoms, generally WITH impairment of consciousness
complex partial seizures
a group of syndromes characterized by unprovoked, RECURRING SEIZURES
epilepsy
one of the main causes of epilepsy that can be prevented
head injury
acute prolonged seizures activity
status epilepticus
